<p></p>
 LatLng is a point in geographical coordinates with longitude and latitude.
  Notice that although usual map projections associate longitude with the
 x-coordinate of the map, and latitude with the y-coordinate, the latitude
 coordinate is always written first, followed by the longitude, as is
 customary in cartography.
  Notice also that you cannot modify the coordinates of a LatLng. If you
 want to compute another point, you have to create a new one.
